Benzene, 1-ethyl-2-isocyanato-3-(1-methylethyl)- (9CI) - Introduction
2-ethyl-6-isopropylphenyl isocyanate, chemical formula C12H18N2O2, is an organic compound. The following is an introduction to its nature, use, preparation and safety information:
Nature:
2-Ethyl-6-isopropylphenyl isocyanate is a colorless liquid with a special odor. It has a density of about 0.97g/cm3 and is insoluble in water. It can be dissolved in many organic solvents, such as ethanol, acetone and toluene.
Use:
2-ethyl-6-isopropylphenyl isocyanate is commonly used as a raw material for synthetic resins in industry. It can be used to manufacture materials such as polymers, elastomers, plastics, adhesives and coatings.
Preparation Method:
The preparation of 2-ethyl-6-isopropylphenyl isocyanate can be accomplished by chlorination of terephthalic acid and esterification with isopropanol. First, phthalic acid is reacted with a chlorinating agent (for example, thionyl chloride) to obtain phthalic acid dichloride. Then, phthalic acid dichloride is esterified with isopropyl alcohol in the presence of a catalyst to produce 2-ethyl-6-isopropylphenyl isocyanate.
Safety Information:
2-Ethyl-6-isopropylphenyl isocyanate is stable under normal conditions, but it is a flammable liquid and should be kept away from open flames and high temperatures. When in use, should wear protective glasses and gloves, and ensure good ventilation. If ingestion or contact with skin and eyes, wash immediately and seek medical advice. During storage and handling, care should be taken to avoid contact with oxidants and strong acids/bases.
